Correct answer: C — Occupational asthma from flour exposure

The temporal relationship between symptoms and work exposure is highly suggestive of occupational asthma. Normal clinic spirometry does not exclude it, particularly between exposures. Serial peak flow readings across work and rest days and early specialist referral are appropriate because continuing exposure can worsen prognosis.
